No-Clean liquid flux, FX16, has been engineered to provide exceptional soldering performance while leaving minimal, electrically safe flux residues, even when unheated. FX16 is ideally formulated for point-to-point selective soldering and palletized wave soldering. FX16 provides fast wetting and PTH barrel fill and reduces common soldering defects such as bridging, flagging, and solder balls. FX16 has a durable activation system that can withstand high process temperatures required for thermally demanding applications and extended solder contact time.

Application
FX16 is formulated for application via spray, brush or dip. FX16 is ready to use directly from its container, no thinning required. When spray fluxing, it is imperative thet proper flux coverage and uniformity be acheived and maintained. A dry flux coating of 900-1500 micrograms per square inch is typical.

Process Guidelines
Using thermocouples attached to the PCB, the topside assembly temperature should be between 80-140°C (175-285°F). It is important that the flux be dry prior to entering the wave regardless of PCB temperature or spattering will occur. Smoke is considered normal if it is not excessive. Recommended contact time with the wave is dependent on wave configuration, pot temperature, alloy type and thermal mass of the assembly wit 3-7 seconds being typical for lead-free applications.

Cleaning
FX16 residues can remain on the assembly after reflow and do not require removal. Where cleaning is mandated, AIM has worked closely with industrial partners to ensure that FX16 residues can be effectively removed with common defluxing agents.

Handling & Storage
FX16 has a sealed shelf life of 1 year when stored at room temperature. Do not store ner flame or fire. Keep away from sunlight as it may degrae the product. FX16 is shipped ready to use, no mixing necessary. Do not mix used and unused chemicals in the same container. Reseal any opened containers. Storage conditions range from 4-40°C (40-100°F).

Safety
Use with adequate ventilation and proper personal protective equipment. Refer to the Safety Data Sheet for any specific emergency information. Do not dispose of any hazardous chemicals in non-approved containers.
